Squealing belt
Howdy all
So I have an 87 Cherokee 4.0 and I've replaced the belt, sanded the pulleys tried to align the power steering pulley etc and it still squeals when it's warmed up. Any ideas?

Balancer seems to be running true. I replaced ps pump and I've aligned and realigned pulley thinking didn't place it right. Do you happen to know the part number for the gatorback belt? Thanks fellas.

Yes, sure still could be a bad belt or one that is not fully tensioned, as the belt on the 4.0 does need to be pretty tight.
But also keep in mind that ANY component along the route of the serpentine belt will start to get noisy as they start to fail. Usually I remove the belt and "hand spin" each of those components to see if I can feel if there is one that isn't turning smoothly......

As mentioned re-check the tightness as these things need to be way tighter than it seems. In the meantime go to the auto parts store and grab some belt dressing. A quick easy temporary (Or sometimes permanent) fix.

I agree. Belt dressing can actually make things worse on a serpentine belt as the dressing hangs on the belt and picks up debris as you drive it. The can of belt dressing I have in my garage (for v-belts only) actually says "not for use on serpentine belts" right on it.....
